Inside the Dirty, Dystopian World of AI Data Centers

Colossus, Elon Musk's data center in Memphis, can consume as much electricity over the course of a year as 200,000 American homes. Tech companies like OpenAI, Meta, Amazon, and Google are building massive data centers to power advanced AI models, requiring vast amounts of electricity that are primarily sourced from fossil fuels. This is leading to a surge in natural gas power plants and the extension of coal plant lifespans. The AI race is projected to drive 2% annual growth in U.S. electricity demand, with some regions facing larger increases. Loudoun County, Virginia, has become a hub for data centers, accounting for 13% of global capacity. While tech firms are investing in renewable energy, they argue it cannot be deployed quickly enough to meet their needs, leading the U.S. government to accelerate permitting for fossil fuel plants. The industry's reliance on natural gas and coal raises concerns about environmental and health impacts, especially in communities like Boxtown in Memphis that already suffer from heavy industry. However, the restart of the nuclear reactor at Three Mile Island shows the industry is also looking to carbon-free energy sources to power the AI boom.
